Kanon has problems with her voice, while Ryo's manager, Shiomi (Tomoya Maeno), has fallen ill. At the hospital, he is turned into the Negative Jeweler, Doguzettsu. Miracle Tunes use the Hip Hop Jewel, but Kanon is unable to resist his attacks. Yuzuhara intervenes to weaken Doguzettsu, and Miracle Tunes defeat him to recover the Jazz Jewel. However, Kanon has lost her voice from exposure to the Negative Aura after the Demon King had shot her.
